We just got a brandnew A200 which is a pretty amazing concept.
Unfortunately the CPU waterpump makes a silent rattle sound. Certainly we know, that most AiO coolers are not silent (you can always hear the pump), but the quiet rattling is usually not there?
Here is a video to get an idea ...

We opened the side panels and visually checked the fans when the system is on. Initially, all fans are NOT spinning and the rattle noise is definitely coming from the waterpump sitting on the CPU.
In a quiet room, you can hear this silent rattle noise everywhere.
The question now is, do other A200 units sound like this?
Is this normal?
